AUTOMATIC CHANGE-MXING DEVICE.

Application led March 8, 1917. Serial No. 153,305.

To all whomt may conce/1m B e it known 'that I, ERNEST H. THOMP- soN, citizen of the United States, and resident of Cambridge, vMassachusetts, have invented certain new and useful Improvements in Automatic Change-Making Devices, of 'which the following is a specification. i

This invention has relation to -automatic coin boxes and more particularly to that class of devices intended to automatically deliver correct change for any denomina tion of coin thatl may be deposited therein.

In devices of this class it is important not only that correct change shall be delivered in return for the particular coin deposited but also that reliable provision shall" be made to prevent the delivery of change upon the deposit of a cointor blank differing even slightly in size from the particular coins that the machine is intended to handle.

The invention consists primarily in a suit-AV able casing provided with a coin chute or passage for the reception of the coin deposited combined with appropriate coin selective and transferringv means by which the app opriate coins are removed to their respective receptacles automatically, certain mechanism being co-ordinated with corresponding change delivering devices whereby upon the deposit of a coin of given denomination they correct change therefor is returned to the depositor, the automatic devices becoming inoperative to deliver change m case a coin or blank not conforming to.

the predetermined size should be deposited in the machine.

This and other features of the invention will be hereinafter described in detail and will be clearly defined in the claims forming part of this specification. v

The machine shown in the accompanying drawings is particularly intended for use in connection with or as part of, an automatic fare box such as is disclosed in my pending ,application for Letters Patent ofthe United States No. 134,864 'filed December 4, 1916. Hence portions of the casing and mechanism forming part of said automatic fare box are incidentally shown in connection with the'present invention which relates onlyv to the automatic change maker.

ln' the accompanying` drawings isillustrated thepreiierredv form embodying the principles of this invention in which, Figure 1` is a rear elevation showing the casing bein" or changeand the change-delivering `operative the automatic mechanism.

gFigure 5 is a plan view of the coin-delivfront elevation of the ma- 00 ering slides or members, the vsurrounding 7 5 shown in horizontal section. Figure 6 is an elevation of the plate carry.

ing the coin-depositing run-ways by which the respective coins transferred thereto by thetransfer. and selective mechanism are conducted tol their respective stacks or con-` tainers. The run-ways on the right-hand side are for the change maker, those on the left-hand side are for the fare box and need not be further considered in this case.

Figure 7 is a side elevation somewhat enlarged showing the automatic mechanism by which the appropriate change delivering slides are actuated through the agency of the coin-transferring mechanism.

Figures 8 and 9 are detail views of the Y locking bolt by which thev mechanism for actuating one of the change slides is locked against accidental operation when it is desired to actuate its'companion slide independently.

Th particular form of change-making device illustrated in the drawings is especially designed to be used in conjunction with my fare boX before mentioned for fare collecting purposes in connect-ion with street railway or other service, and for. that reason inasmuch as the casing embraces both an automatic'fare boX for receiving and registering fares and an independent change maker arranged side by side, the casin is given a form and construction ditferlng somewhat from that to be used in case the change maker is constructed as a physicall separate unit. It lshould be explainec, therefore, that the hopper shown at the top of theireceptacle with a central funnel-like chamber is used in connection with lthe fare box and not in connection with the change maker.

Before giving a detail description itwill aid to an understanding to state that the coin to be changed, say in this casel a halt' dollar, a qua-rter dollar or a dime. is deposited in the receiving aperture or chute shown at a to a narrow vertical passage a formed between two parallel closely arranged vertical partitions in which are located a series of projecting ledges or lingers which form th'e terminals ot' tliree parallel or shunt circuits which include the coilv of an electroma-gnet ,c by which automatic action is controlled as will be hereinafter explained. The coin resting on either pair of ledges will complete that particular circuit and energize the coin transferring mechanism to carry the coin rearwardly into an interior compartment a3 whence through the appropriate run-ways the coin is conducted to its final destination. The movement of the coin transferring mechanism in transferring any particular coin to the interior compartment acts to set in operation the appropriate change-delivering slide or member to deliver through the front outlet (12 the appropriate change from interior coin stacks.

It is to be understood that the depositor has nothing to do beyond deposit-ing his coin and receiving his change from the outlet or change-delivering chute since the entire. action ot' transferring the coin to its appropriate receptacle and the delivery of the change through the outletchute is automatically set in opera-tion through the agency of the particular coin deposited which acts to close an energizing electricy circuit which furnishes the motive lpower rfor the various parts ot' the mechanism.

As best shown in Figure 3 the selective passages and apertures are enclosed within a front wall and a rear wall f each of which is provided with a series ot' bearing apertures b f respectively, arranged in vertical alinement to permitI the movement of the plungers or push rods forming part of t-he transferring mechanism.

Immediately behind the front wall and at a distance not much greater than the thickness of the largest coin to be handled, is placed a vertical partition c which acts .the receiving slot (Fig. 4) through which it rollsl c magnet .r

as a guide to enclose the vertical run-way or chute a into which the coin drops from or passage cz. A series of supporting fingers or ledges are arranged in opposing pairs on opposite sides' ofthe apertures formed in this partition for the passage ot' the coin. The lowerlnost pair ot' fingers b4 are spaced apart so as to be separated by a distance only very slightly less than the smallest coin to be handled, in this case a dime. The next higher pair ot' ledges or coin supports b3 are spaced apart a distance only slightly less than the di-v ameter ot' a quarter dollar so that the dime will tall between them while t-he quarter will be arrested and supported on their opposed ends. The uppermost pair of ledges are spaced to allow the other coins to pam f between while retaining the half dollar.

The respective ledges are mounted on strips of insulation so that the respective circuits of which they torni interrupted terminals will be closed by the Contact of the coin supported thereon. These several electric circuits are connected with an electr whose core is energized by the closing of its circuit to attract a pivoted armature member .r2 which engages a switch member a whose upward movement closes the terminals 1/ of the elec-tric circuit of solenoid l/ whose plunger t1/2 is normally held upward by a compressed spring 1/3 when the solenoid is inactive. The energizing of the solenoid circuit. acts to draw down the plunger 3/2 which acts through suitable connections. which will be described later. t'or the purpose of setting in operation the 'various parts ot' the mechanism. l

I prefer to employ a relay magnet for controlling the solenoid because it a heavy current. such as would commonly be used for actuating the solenoid. were to be closed through the contact of afdeposited coin. the arcing of such current would injure the coin.

Back of the partition c is another vertical partition or wall 17 having a series of vertically alined apertures a2. a4, (z7 opening into the run-ways or compartments a3, a, as. respectively. formed by dividing ribs which project rearwardly from the rear or back surface of said partit-ion wall. These. apertures are preferably formed in inserted rings tapered to a narrower diameter toward their rear ends which narrow diameter, corresponds closely to the diameter'of the particular coin intended to pass through such aperture so as to form a selective passage or opening capable of rejecting Ioins that are appreciably larger than the particular coin for which said aperture is intended. ln this case the ring aperture a is intended for a half roller. rz* for a quarter dollar and a7 fordimes.

1o front bar m,

siens g4, g5,

30 turned to normal rods h, h and h2 which are securely fastened in a. vertical bar mechanism of a reciprocating cross-head which comprises the a rear barm and upper and lower connecting tie-rods m2.

Idler `plungers gag', g2 are each ofmthem. mounted in a hollow bearing g3 secured to the. rea-r wall f and Vhaving rear-ward exteng6 in which are inserted laterally pro]ecting pins gf which are arranged to engage the adjacent free ends of bell crank levers j, j', 7'2 mounted on a series of horizontal shafts 73 by which the respective change delivering slides are actuated to deliver change.

The rear upright or bar/m of the-reciprocating cross-head is provided witha s'eries of vertically aligned thrust screws or abutting screws gm which are horizontally aligned with the rearward extensions g4, g, g of the respective plungers so that on the. return movement of the cross-head in a forward direction the idler plungers are resition, indicated in Figure 3. 'Ihe crossead is moved rearwardly bythe rotation of a rock shaft o to which is secured an upright arm or lever o pivotally connected with a link o 2 whose rearward end is pivotally connected to the bar fm of the cross-head, said arm and link forming 'a sort of toggle joint which acts to move the crosshead rearwardly when the rock shaft is partially rotated by the downward movement 40 of the solenoid plunger. The solenoid plunger is slotted and provided with a cross pin ya which is engaged by a forked lever g2- secured to said rock shaft o. When the solenoid y is energized through the closing of its circuit b means of the relay switch w3 it acts topu l down the plunger y2 which inturn partly rotates ithe rock shaft o thus moving the cross head rearwardly.

So long as n'o coin is interposed between thepush. rods secured tothe front bar of the cross-head and the aligned idler plungers the movement of the cross-head will produce no corresponding movement of the idler plungers, because in such case all the push rods will telescope `into the recesses formed in the front ends of the respective idler plungers. It will, of course, be understood that no such movement of the cross-head can take place anyway unless there is a coin resting upon a pair of the coin-supporting circuit terminals or ledges.

Let us suppose that a half dollar be dropped into the machine and finds its way through the inlet chute a to the upper pair of ledges b2. At once the circuit of the relay magnet is closed by the contact (if the coin on said ledges thereby causing the switch w3 Ato close the solenoid circuit andtoenergize the. solenoid coil so as to depress the plunger. 1/2. The'cross-head then begins to move rearwardly until/the push rod h, by pressingthe coin against the frontend of theidler' plunger. g, forcesrt-hat particulamfidler plunger back Athrough the apertured ring a2,` the half dollar being carried with it owing to the pinching pressure exerted by the push -rod h. When the cross-head has reached the limit of its rearward movement the return movement of the plunger due to the expansion of the vcompressed helical spring ya, serves vto release the coin from thispinching action between the pus rod and its plunger, and hence the coin fa ls into the-ruii-wayor passage a3, by which it is conducted to a receptacle in the bottom of the machine. As

4shown in the drawings,` there -is sufficient clearance Ito" ive a slight` lost motion between the o set abutments of the crosshead comprising the push rod hand .the abutment screws 91 so that the idler plunger doesnot-begin to move until after the push rod has made a slight rearward traverse and does not begin to return to normal position -until after the abutment screw gl has vmoved forward for a similar distance, the object of this clearance being to ensure complete release of theA coin from the two pinching members. Thefriction of thesupporting bearing which carries the idler plunger gives it suflicient inertia to enable it to act with entire reliability.

In this operation the 4ther idlerr plungers have .not beenactuated owing to the fact that no coinis present on their respective' ledges and hence their respective push rods are free to telescope -ilitothe forward recesses without causing anyv movement of tube a25 which also forms the reservoir for containing and delivering change. The lowerniost pair of cooperating plungers act upon the dime to transfer it through vthe aperture a7 into the run-way passage a8 which lea-ds to the coin stack am.

A coin that is larger' than a half dollar cannot pass below the uppermost ledges b2` and cannot pass through the gauge orifice or ring a2.' It will, however, act to close the .circuit between the led es b2 and cause the cross-head to move. n order to prevent clogging the machine', the 'apertures in the partition c are made amply large `to permit a blank larger than the intended coin to pass through to the rear of said partition c and as said coin cannot continue its movement through the partition Z owing to the intermediate the smaller size of the gauge r` or aperture a2 it must drop in the vertical space between the partitions c and d at the bottom of the machine. Since the cross-head cannot under such circumstances make a full rearward traverse, no change is delivered on this partial movement. However, since the solenoid 'acts with ay powerful pull, to prevent breakage or injury to the parts, l prefer toconnect the forked lever g2 to the rock shaft a bymeans of a yielding connection. As 'shown in 4Figure 12 the lever g2 is loose on the rock shaft o and is operatively connected therewith by means of spring pawls g'21 en aging notches in a gauge disk or hub 922 fgastened to said rock shaft. Thisengagement is sulhciently strong to actuate'the cross-head under nor'- mal conditions but is', also capable of yielding to allow the lever g2, which is positively connected to thesolenoid lunger, to continue its movement in case t e further movement of the cross-head is blocked or obstructed by a coinor blank too large to pass through the apertured gauge ringog. Thus the solenoid completes its downward movement and is returned by its compressed spring to normal i position. This [return movement releases the obstructing blank allowin it to --fall between the partitions c and ,g to the bottom for recovery by the depositor.

The switch Les is disengaged from the solenoid circuit terminals by the downward movement of the pin y by the thrust of the yielding spring y interposed between the head 15 and the tubular plunger g/Z against which the solenoid plunger y2 is forced. 0n the return of the `lunger y2 the pin y is restored to normali the light helical sprin 1. ment eases the shock o noid plunger.

This arrangelmpact of the so e- The change to be delivered is contained in three vertical stacks a, al, a containing respectively, nickels, 'dimes and quarters, the stacks being arranged side by side across the machine and having their upper ends as well as their lower ends open. Beneath the ower ends of the three stacks is a bed plate p above which on the side beneath the stack ams is .mounted a horizontal slide p having an aperture of a size to receive a single quarter, the plate being substantially of the same thickness as a quarter dollar. Said bed plate has near its iront edge or end three apertures odset rearward y from the vertical stacks but in the same vertical planes as apertures being of a size to permit the respective coins to pass through into the outlet or change deliverin chute a2". Obviously when the slide p containing a single quarter is pushed forwardly until its aperture au with the aperture 1n the position by` the respective stacks, saidl the change stack is empty I provide device oonsistingof a pair of toggle bers n,

Furthermore while the dime slide and the nickel slide may act while the-quarter slide is at rest,"yet the actuating `connections hereinafter explained make -it ,necessary` that both the dime land the nickel slides simultaneously with the quarter slide whenever the' quarter slide is actuated.

The result of this arrangement is that on'the deposit of a dime, 'two nickels are automatically returned'to the depositor for change but on the deposit of a quarter one dime and three nicke s 4are returned to the depositor. On the deposit of 'tycents theI depositor receives one' quarter dollar, .one dime and-three nickels.

. I will now explain the actuating connections by which the slide movementsl are controlled for delivering change.

The nickel slide p* has a rearwardly ex-v tending actuating rod p14 connecting to the downwardly extending forked arm p24 of* a bell crank lever pivotallyattached to. upper end is pivotal crank lever i2 that is actuated by the extension g6 of the dime actuated plunger g2. Obviously the rearwalrd movementy of the plunger dig? rocks the bell crank lever i2 rearwar y, thereby depressing the link r and causing the connecting rod p. to move forwardly `which forces the nickel slide forward until its nickel containing aper-4 ture registers with the corresponding aperture in the bed 'plate p to allow theltwo nickels therein to fall into the chute a2".

In the same mannerthe rod p12 is moved forward by the bell crank level p22., p92, when the link 1'" which connects arm p32 is depressed by the rearward motion of the plunger g5. In a similar manner the slide rod p is moved forward the extension p3 in'order to nickel stack. It will be un- 4 w|hose upper arm. p34 is. As soon,

a vertical link r whose 1y connected to the beuf ing engagement with the hook 83, thereby through the connecting arms '1121, p31, the link r? andthe arm j which is actuated by the'uppermost lungervg ag inst which the 'half dollar is forced. s

,It isto bezturthernotedl that the arm p3* has a laterally projecting finger p35 overlapping the 'arm p32 vso that the arm p3* while free to. move whenthearm p32 is at rest, must-necessarily be moved by the downward movement of the arm 11??, thus causing both arms, and consequently both the dime vand nickel yslides to .be actuated simultaneously.v It willv Aalso be noticed that the arm p32 has a similar and laterally extending lfinger p38; overlapping the arm so that whenever the arm puis actuated,

the arm p32 must alsoV be .simultaneously actuated and likewise the arm p84.'

Io prevent the dime slide p2 from being moved by Vfrictionalv engagement when the "nickel slide p*- alone is intended to be actuated, I provide a locking device forpositively locking the dime slide delivering-mechanism in such case. yAs shown in Figure 8, this lockingdevce comprises a vertical slide bolt s having an elongated aperture s at its upper end and ya'projectingpresser rfoot or arm 82 at its lower end. On thev vertical arm ofithe'lever "j" (Fig". 7*) is Asecured a hook .93 arranged to pass into the aperture of the bolt s when thel bolt is in raised position.

When the bolt is lowered-it engages the hook.

andA looks the lever against movement. The bolts 1sF normally pressed downwardly b` meansv of a compressed springV .95 (Fi'g.y 9g,

The coin slides are preferably madel of a The'rearward plunger exthe bolt from becoming operative.`

To empty all of the coin stacks in order to i recover the coin thereinthe bed plate'p may thickness-corresponding to the thickness of a normal com or coins that' thev slides are intended to carry. It often happens, how? ever, that lthe thickness 'of a coin is materially reduced by wear. In ythat case when the coin aperture in the slideis in register with the open lower end of the coin stack,

the next coin above the coin contained in the slide may project slightly into the slide below its upper face. y This would be likely to clog the slide and prevent it from operating. To avoid this difficulty the slides adjacent to one side of the apertures are bevelled or thinned down as indicated in Figures l0 and 1l at p3", the reduced or thin edge being cut down sufficiently to prevent the slide from having greater thickness at that point than such va worn coin would have. Y The result is that when the slide movesback to deliver a coinfrom the change stack this edge of the coin aperture will not engage the next higher coin while the bevelled portion at p39 will act as a wedge to force up the superimposed coin above the level of the body of the slide so as to allow the slide to move back without an obstruction. This is an important detail of the invention since withoutthis or some equivalent arrangement it is ob-i vious that a thin or worn coin could block the operation of the change slide, as Will be apparent from an inspectioniof Figure l1 which shows in dotted lines the position of the two lower coins when the lowermost coin is thinner than normal.
